Answer 1

Answer:

check it out

Step-by-step explanation:

3x+4y=10------------------------eqn 1

x-y=1-------------------------------eqn 2

multiplying 3 on eqn 2

3(x-y)=3*1

3x-3y=3--------------------------eqn3

by subtracting eqn 1 frm eqn 3

3x-3y=3

3x+4y=10

-    -       -

_______

-7y=-7

=y=1

hence x=2
